At many Unis you wont get this far - it will be 'suggested' to you that you find a better way to waste your time (and theirs) long before your final year.
Essentially, its worthless. If anything it reveals everything you'd rather an employer didn't know - that you arent very bright, you are lazy and you enjoy wasting time. Anyone adding it to their CV is hardly doing themselves a favour and would be better off hiding their degree certificate in their sock drawer and pretending they'd 'been travelling' for the last three years.
